KVM: x86/mmu: Fix uninitialized boolean variable flush
In the case where kvm_memslots_have_rmaps(kvm) is false the boolean
variable flush is not set and is uninitialized. If is_tdp_mmu_enabled(kvm)
is true then the call to kvm_tdp_mmu_zap_collapsible_sptes passes the
uninitialized value of flush into the call. Fix this by initializing
flush to false.
Addresses-Coverity: ("Uninitialized scalar variable")
Fixes: e2209710ccc5 ("KVM: x86/mmu: Skip rmap operations if rmaps not allocated")
